Assembly method of a plant for gas separation

Abstract

The invention relates to an assembly method of a gas separation device comprising at least a separating column (1) and a casing device for bounding the separation column (1). The separation column (1) is manufactured in advance in a manufacturing factory and is equipped with a pipe bridge module. The column (1) is horizontally supported on a construction site so that the pipe bridge module (2a-2d) is mounted on an upper part of an outer casing along a parallel axis to a preferable axis of the separation column (1). Thus the pipe bridge module (2a-2d) can be fully or partially mounted on the peripheral surface of the separation column and accessory portions are mounted in the manufacturing factory or on the construction site. Accessories are at least partially assembled on the pipe bridge module (2a-2d) when the separation column (1) is horizontally supported. Only a small scaffold in the separation column (1) diameter height is needed by assembling the accessories in the horizontal orientation. Almost all the work is done in a plain place. In parallel with the horizontal assembly of the accessories on the separation column (1), the casing device is processed to half of the height in vertical direction, wherein the upper part is kept open. After the separation column (1) is pricked as a vertical orientation and is guided in the casting device from above, the assembly is finished and the casing device is closed.

Description

technical field [0001] The invention relates to a method for assembling a gas separation device comprising at least one separation column and a jacket surrounding the separation column, wherein the separation column has a preferred axis and various fittings fastened thereto, Examples include pipes, inlet and outlet devices, valves and / or instruments. Background technique [0002] In the construction of a gas separation plant, for example a cryogenic air separation plant, there is basically the option of prefabricating the plant as far as possible in a factory workshop or assembling the plant components only on the construction site. In the first case, due to the large size of the separation column of such devices, transportation is often cumbersome. The second option requires extensive assembly work in less than ideal circumstances. An important part of the assembly is placing a separation column in an enclosure, such as a cold box for insulation. [0003] As background a...

Problems solved by technology

In the first case, due to the large size of the separation column of this equipment, it is usually difficult to transport

The second option requires a lot of assembly work to be performed in a not-so-suitable environment

This substantially increases the structural complexity in the case of externally accessible components
